What is Roller Bearings
Plain bearings are bearings that work under sliding friction.Roller Bearings work smoothly, reliably and noiseless.Under the condition of liquid lubrication, the sliding surface is separated from the lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear, and the oil film also has a certain vibration absorption ability.
Characteristics of Roller Bearings
Roller Bearingscan absorb and transfer the forces between the relative moving parts to maintain the position and positioning accuracy of the two parts.Commonly used Roller Bearings materials include bearing alloy, wear-resisting cast iron, etc.
Application of Roller Bearings
Roller Bearings are mainly used in low-speed and heavy-duty applications.For example: construction machinery, Marine equipment, water conservancy engineering, aerospace, railway and other fields.
Analysis of the reason of Roller Bearings axle
1.There are impurities, dirt and poor oil cleanliness in the lubricating oil and Roller Bearings oil pool.When the oil ring rotates with the spindle, the oil supply system begins to work.When impurities and dirt drag the spindle or Roller Bearings, non-liquid friction is easy to occur, resulting in shaft holding.
2. The lubrication system of the grinding head fails.When the oil ring rotates with the spindle, the hole on the oil ring splatters the lubricating oil in the oil pool, and the lubricating oil splatters on the spindle, and the spiral oil groove on the spindle inputs the lubricating oil between the spindle and the Roller Bearings.When the lubricating system of the grinding head does not supply oil or the oil supply is not stable, the phenomenon of holding the shaft will occur.
Repair of Roller Bearings after shaft locking and measures to prevent shaft locking
1. Install the rear bearing pedestal, rolling bearing and bearing outer spacer inner spacer on the spindle.
2. Place the grinding head body vertically without Roller Bearings, and measure the radial runout of the spindle ≤0.1mm.The dial gauge seat is drawn at the spindle end, the dial needle points to the inner diameter of the front bearing seat, and the spindle and the front bearing seat are coaxial ≤0.02mm.If the measured value is out of tolerance, the inner and outer ring of the bearing should be readjusted and the rear end face of the head body should be repaired until it meets the requirements.
3. Spindle and Roller Bearings should be scraped.
4 Roller Bearings according to the requirements of the injection of lubricating oil, the application of silk filter.
